network_replay ~425
Re-issue a request the app already made, optionally with changes. PURPOSE: Retry a captured call without driving the UI back to the screen that made it — and vary one field at a time to find what the backend actually rejects. WHEN TO USE: A request 4xx'd and you want to know whether it was the body, a header, or the endpoint. Or a flaky call you want to run again. WORKFLOW: get_network_requests -> copy the id -> network_replay({requestId:"js-x1-7"}) -> network_replay({requestId:"js-x1-7", body:"{...}"}). GOES THROUGH THE APP: same network stack, TLS trust, proxy and credentials as the original — cookies are attached by the native cookie jar, so a cookie-authenticated call replays as the logged-in user with no token handling. An active network_mock rule will intercept the replay too; the response says so when it does. LIMITATIONS: ids come from get_network_requests and expire when the buffer rolls over or clear_network runs. Headers replace wholesale, they do not merge. GOOD: network_replay({requestId:"js-x1-7", body:"{\"qty\":99}"}) BAD: guessing a requestId — read one from get_network_requests first.
| Name | Type | Req | Description |
|---|---|---|---|
| auth | string | – | Default "none": the captured headers already carry the original Authorization. Use "auto" to resolve a fresh token instead. |
| body | string | – | Replace the captured request body. Sent verbatim, already-encoded. |
| device | string | – | Target device name (substring match). Omit for the default device. |
| headers | object | – | Replace the captured headers entirely (not merged). |
| maxResultLength | number | – | Target size for the returned body in characters (default 25000). |
| method | string | – | Override the captured HTTP method. |
| requestId | string | yes | Id of a captured request, from get_network_requests or search_network. |
| url | string | – | Override the captured URL. |

pinch ~800
Pinch-to-zoom using REAL two-finger touch events, with pixel-diff verification. ANDROID EMULATOR ONLY (iOS in progress). [PRIMARY INTERACTION TOOL — works on iOS and Android; prefer over ios_*/android_* siblings] PURPOSE: Zoom a map, image gallery, photo viewer, or any zoomable surface. pinch({ direction: "out" }) zooms in at screen centre; "in" zooms out. Pass x/y to zoom around a specific point. HOW IT WORKS: Two independent contacts sent through the emulator's multi-touch bridge as real kernel touch events. It works below the app, so it drives React Native, native views, WebViews — anything on screen. VERIFICATION: verify=true (default) returns `verification.meaningful` — false means nothing zoomed (not zoomable, already at a zoom limit, or the focal point missed). WORKFLOW: pinch({ direction: "out" }) -> read verification.meaningful. Take x/y from get_screen_state or a screenshot; no conversion needed. IF A GESTURE DOES NOTHING: lower `span` — the contacts may be landing on surrounding UI (a top bar, a bottom sheet) rather than the zoomable surface. direction="in" already defaults to a reduced span for this reason. LIMITATIONS: Physical Android devices and iOS have no multi-touch channel and return an explicit error, never a partial result. Success means real fingers moved — this never fakes zoom by calling app code.
| Name | Type | Req | Description |
|---|---|---|---|
| angle | number | – | Axis the two fingers sit on, in degrees. 0 = horizontal (default), 90 = vertical. |
| burst | boolean | – | Capture rapid sequential frames after the pinch to catch transient feedback (rubber-band snap-back at a zoom limit) even when the final state is unchanged. Frames land in the image buffer; retrieve w… |
| device | string | – | Target device. Accepts (a) an Android adb serial like 'emulator-5554', (b) the emulator name (substring match), or (c) a connected RN app's deviceName (substring match against get_apps output). Omit… |
| direction | string | – | "out" spreads the fingers apart and zooms IN (default). "in" brings them together and zooms OUT. |
| durationMs | number | – | Gesture duration in milliseconds (default: 300). |
| scale | number | – | How far the fingers travel, as a ratio between their start and end separation. Default 3. Large values are split automatically into several chained gestures. |
| screenshot | boolean | – | Return the post-pinch image bytes in the response. Default true. Set to false to drop the PNG bytes — verification still runs (set verify=false to skip that too). |
| span | number | – | How much of the screen the gesture occupies, as a fraction 0-1. Defaults to 1 for direction="out" and 0.5 for direction="in", because a pinch-in starts with the fingers far apart and at span 1 they l… |
| verify | boolean | – | Compare before/after screenshots to detect whether the pinch produced a visual change. Set false to skip. When skipped, the response contains `verification: { skipped: true, skippedReason }`. |
| x | number | – | Focal point X in screenshot pixels — the point the zoom centres on. Default: screen centre. |
| y | number | – | Focal point Y in screenshot pixels — the point the zoom centres on. Default: screen centre. |

redux_dispatch ~509
Dispatch a Redux action to the store bound to the app's <Provider>, triggering useSelector subscribers and React re-renders. Resolves the live store by walking the React fiber tree on each call (no SDK setup needed; works even if no store was registered with init()). PURPOSE: Drive state-controlled UI (loaders, modals, toasts, error overlays) without exercising the real flow (network, OTP, etc.). WHY THIS EXISTS: __RN_AI_DEVTOOLS__.stores.redux often holds a different store reference than the one passed to <Provider>, so dispatching through it updates state but does NOT notify react-redux subscribers. This tool dispatches through the actual Provider store, so views re-render. WHEN TO USE: Verify state-driven UI by seeding redux state directly. Example: dispatch app/setIsLoading: true, then ios_screenshot to confirm the loader rendered. WORKFLOW: redux_dispatch({ action: { type: 'app/setIsLoading', payload: true } }) -> ios_screenshot -> redux_dispatch({ action: { type: 'app/setIsLoading', payload: false } }). BATCH: action accepts an array — dispatched in order, one round trip. LIMITATIONS: Requires React DevTools hook (dev mode). Action must be plain JSON-serializable (no thunks/functions). If the app has multiple <Provider> roots, pass storeIndex (default 0). GOOD: redux_dispatch({ action: { type: 'app/setIsLoading', payload: true } }) BAD: redux_dispatch({ action: () => ... }) — actions must be plain objects; for thunks use execute_in_app to call your action creator.
| Name | Type | Req | Description |
|---|---|---|---|
| action | – | yes | Plain JSON-serializable Redux action object, e.g. { type: 'app/setIsLoading', payload: true }. Pass an ARRAY to dispatch several in order in one round trip — restoring a 17-field settings slice is on… |
| device | string | – | RN device name (substring). Omit for default; see get_apps. |
| returnPath | string | – | Optional dotted path into the post-dispatch state to return for verification (e.g. 'app' or 'auth.user'). Omit to skip returning state — keeps the response small. Use redux_get_state for ad-hoc reads. |
| storeIndex | integer | – | Index of the Provider store to dispatch to when the app has multiple <Provider> roots (default: 0). |
No output schema declared.
No examples provided.
redux_get_state ~515
Read state from the Redux store bound to the app's <Provider>, resolved live via the fiber tree (same store redux_dispatch targets). PURPOSE: Inspect the current app state without relying on __RN_AI_DEVTOOLS__.stores.redux (which may point at a different store instance than the Provider). WHEN TO USE: Verify state shape before/after redux_dispatch, or check what slice keys exist before crafting an action. WORKFLOW: redux_get_state() -> craft action -> redux_dispatch -> redux_get_state({ path: 'app' }) to confirm. SHAPE FIRST: a large state comes back as its structure — every key path kept, arrays and objects annotated with real sizes, leaves clipped. Read it, then narrow. NARROWING, TWO WAYS: path drills IN THE APP, so the rest of the state never crosses the wire — prefer it when you know the slice. query runs here and adds [0], [-1], [*] and quoted keys. They compose: path picks the slice, query picks the field inside it. LIMITATIONS: Requires React DevTools hook (dev mode). State must be JSON-serializable; non-serializable values are replaced with an error marker. GOOD: redux_get_state({ path: 'app' }) | redux_get_state({ path: 'cart', query: 'items[*].sku' }) BAD: redux_get_state({ path: 'app.isLoading.0' }) when isLoading is a boolean — path traversal returns undefined.
| Name | Type | Req | Description |
|---|---|---|---|
| device | string | – | RN device name (substring). Omit for default; see get_apps. |
| maxResultLength | number | – | Byte target for the rendered state (default: 25000, 0 for unlimited). Bounded structurally, so size is traded for depth and array width rather than cutting the text off. |
| path | string | – | Optional dotted path into state (e.g. 'app' or 'auth.user'), resolved in-app so only that slice crosses the wire. Omit for the full state. |
| query | string | – | Dot-path into the state that came back, returned in full: "items[0].sku", "orders[*].status", "byId[\"a.b\"]". Applies after path. A path that matches nothing returns the shape plus what is actually… |
| storeIndex | integer | – | Index of the Provider store to read from when the app has multiple <Provider> roots (default: 0). |

No examples provided.
reload_app ~343
Reload the React Native app (triggers JavaScript bundle reload like pressing 'r' in Metro). PURPOSE: Force a full JS bundle reload when Fast Refresh isn't enough — clears in-memory state and re-runs the bundle from scratch. WHEN TO USE (only these cases): (1) native code, app.json, Info.plist, Podfile, or a native module changed; (2) Fast Refresh visibly failed (red-screen or stale render confirmed via screenshot after a few seconds); (3) the app is in a broken state; (4) you need to reset app state completely; (5) the user explicitly asks. AVOID: reloading reflexively after JS/TS/TSX/style edits — Fast Refresh applies those in 1-2s. A reload discards navigation stack, context, hooks state, BLE/WebSocket connections, paired devices, and auth sessions, which can force re-pairing or re-login and break your verification loop. WORKFLOW: screenshot → wait 2s for Fast Refresh → if still stale, reload_app. Auto-connects to Metro if no connection exists (with or without a device argument) — no need to call scan_metro first. After reload, wait a few seconds before running other tools. SEE ALSO: get_refresh_status (did Fast Refresh accept?), get_bundle_status (did Metro compile?).
| Name | Type | Req | Description |
|---|---|---|---|
| device | string | – | Target device name, substring match against the name shown by get_apps (a simulator UDID or adb serial also works). OMIT THIS unless several devices are connected — passing a name copied from list_de… |
No output schema declared.
No examples provided.
scan_metro ~226
Scan for running Metro bundler servers and automatically connect to any found React Native apps. This is typically the FIRST tool to call when starting a debugging session - it establishes the connection needed for other tools like get_logs, list_debug_globals, execute_in_app, and reload_app. PURPOSE: Discover Metro on ports 8081-8090 and auto-connect all React Native debugger targets it advertises. WHEN TO USE: At the start of any session, or after the user restarts Metro / boots a new simulator. WORKFLOW: scan_metro -> get_apps -> get_logs / ios_screenshot / tap. GOOD: scan_metro() BAD: scan_metro() called repeatedly in a loop — use ensure_connection to re-verify an existing connection.
| Name | Type | Req | Description |
|---|---|---|---|
| endPort | number | – | End port for scanning (default: 8090). Metro allocates upward from 8081, so ten ports covers several apps side by side; widen only if your bundler is pinned elsewhere. |
| startPort | number | – | Start port for scanning (default: 8081) |
No output schema declared.
No examples provided.
search_logs ~242
Search console logs for text (case-insensitive). PURPOSE: Find log lines matching a substring across the connected app's console buffer. WHEN TO USE: User reports a known error/warning, or wants to trace a specific event (e.g., "redux", "auth failed"). For unfocused exploration, prefer get_logs. WORKFLOW: scan_metro -> search_logs(text="...") -> if empty, get_logs to verify buffer populated. LIMITATIONS: Only matches text captured AFTER the app connected; won't find pre-connect logs. GOOD: search_logs({ text: "TypeError" }) BAD: search_logs({ text: "" }) (use get_logs for a raw dump)
| Name | Type | Req | Description |
|---|---|---|---|
| device | string | – | RN device name (substring). Omit for all devices; see get_apps. |
| maxMessageLength | number | – | Max characters per message (default: 500, set to 0 for unlimited) |
| maxResults | number | – | Maximum number of results to return (default: 50) |
| text | string | yes | Text to search for in log messages |
| verbose | boolean | – | Disable all truncation and return full messages |
No output schema declared.
No examples provided.
search_network ~249
Search network requests by URL pattern (case-insensitive). PURPOSE: Filter the network buffer to requests whose URL matches a substring — fast way to find a specific endpoint in a noisy app. WHEN TO USE: You know part of the URL (e.g., "/graphql", "users", a domain) and want matching requests across all devices. WORKFLOW: search_network(urlPattern="/api/") -> get_request_details(requestId="...") for full headers/body. LIMITATIONS: Matches URL only; for method/status/body filtering use get_network_requests. Bodies are only present when the SDK is installed. GOOD: search_network({ urlPattern: "/graphql" }) BAD: search_network({ urlPattern: "" }) — empty pattern matches everything; use get_network_requests instead.
| Name | Type | Req | Description |
|---|---|---|---|
| device | string | – | RN device name (substring). Omit for all devices; see get_apps. |
| maxResults | number | – | Maximum number of results to return (default: 50) |
| urlPattern | string | yes | URL pattern to search for. Also matches GraphQL operation names (e.g. "GetCharacters") — use the operation name to find one GraphQL call among many sharing the same endpoint. |

No examples provided.
send_feedback ~304
Report feedback about the ExecBro MCP tools THEMSELVES — a tool (tap, get_screen_layout, get_logs, etc.) that behaved incorrectly, was confusing, was missing, or could work better. This is EXCLUSIVELY about your experience operating ExecBro's debugging tools. It is NOT for bugs in the user's app under test, and NOT for the feature or task you were working on in this session — keep that out of the report entirely. Auto-collects environment info. Returns a pre-filled GitHub issue URL and formatted issue body. Ask the user to open the URL and paste the body to submit.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | What about ExecBro's tools went wrong or could be better: which tool, what you expected it to do, what it actually did. Do NOT describe the app feature or task you were debugging — only the tool's be… |
| title | string | yes | Short summary of the ExecBro tooling issue (becomes the GitHub issue title) |
| type | string | yes | Type, scoped to ExecBro tooling: "bug" = an ExecBro tool malfunctioned, "feature_request" = a missing ExecBro capability, "feedback" = general notes on using the ExecBro tools |
| workflow_context | string | – | Which ExecBro tools were in use when the issue surfaced (e.g. "tap → get_screen_layout retry loop"). Name the tools and the debugging step — not the user's app goal. |

swipe ~806
Swipe gesture that auto-routes to the correct platform (iOS or Android), with pixel-diff verification. [PRIMARY INTERACTION TOOL — works on iOS and Android; prefer over ios_*/android_* siblings] PURPOSE: Single unified swipe entry point. Easiest form: swipe({ direction: "up" }) scrolls to reveal more content ("down"/"left"/"right" also work; bare swipe() defaults to "up"). Optional distance in screenshot pixels (default 33% of axis). For precise control, pass all four coordinates (startX/startY/endX/endY) — they take precedence over direction. WHEN TO USE: Scrolling lists, paging carousels, pull-to-refresh, dismissing sheets, opening drawers. Especially useful in virtualized lists (FlatList/SectionList) where off-screen items aren't mounted in the fiber tree. VERIFICATION: verify=true (default) returns `verification.meaningful`. When false, `warning` names the cause — already at top/end, not scrollable, wrong axis, no scroll view there, or (no RN connection) that it could not inspect the screen. burst=true catches transient feedback like overscroll bounce. SAFETY: Android direction swipes stay clear of the system bars; `foregroundLost` appears if the app left the foreground anyway. WORKFLOW: swipe({ direction: "up" }) -> read response.verification.meaningful. LIMITATIONS: iOS needs AXe (brew install cameroncooke/axe/axe) or IDB. Pass `device` to target a specific device — call list_devices for the inventory.
| Name | Type | Req | Description |
|---|---|---|---|
| burst | boolean | – | Capture rapid sequential frames after the swipe to detect transient feedback (overscroll bounce, fling-then-snap-back) even when the final state is unchanged. Frames are stored in the image buffer; u… |
| delta | number | – | iOS only — touch step size between events (driver-dependent default). Ignored on Android. |
| device | string | – | Target device. Accepts (a) an iOS simulator UDID, (b) an Android adb serial like 'emulator-5554', (c) the iOS simulator or Android emulator/device name (substring match), or (d) a connected RN app's… |
| direction | string | – | Shorthand for a centered scroll gesture (content-scroll semantics): "up" reveals content below (finger moves bottom→top), "down" reveals content above, "left"/"right" page horizontally. A bare swipe(… |
| distance | number | – | Travel length in screenshot pixels for the direction shorthand. Default: 33% of the relevant screen axis. |
| durationMs | number | – | Swipe duration in milliseconds (default: 300 on Android; iOS uses driver default if omitted) |
| endX | number | – | Ending X coordinate in screenshot pixels (explicit-coordinate mode) |
| endY | number | – | Ending Y coordinate in screenshot pixels (explicit-coordinate mode) |
| screenshot | boolean | – | Return the post-swipe image bytes in the response. Default true. Set to false to drop the PNG bytes — verification still runs (set verify=false to skip that too). |
| startX | number | – | Starting X coordinate in screenshot pixels (explicit-coordinate mode) |
| startY | number | – | Starting Y coordinate in screenshot pixels (explicit-coordinate mode) |
| verify | boolean | – | Compare before/after screenshots to detect whether the swipe produced a visual change. Set false to skip. When skipped, the response contains `verification: { skipped: true, skippedReason }` so calle… |

tap ~1,115
Tap a UI element. Automatically tries multiple strategies: fiber tree (React), accessibility tree (native), and OCR (visual). [PRIMARY INTERACTION TOOL — works on iOS and Android; prefer over ios_*/android_* siblings] PURPOSE: Single unified tap entry point — resolves text/testID/component/coordinates into a real touch event on the correct device. WHEN TO USE: Any time you need to press a button, focus an input, open a menu, or verify a handler fires. Prefer testID, then text, then component, then (x,y) from a screenshot's pressables list. WORKFLOW: ios_screenshot or android_screenshot -> tap(testID="...") | tap(text="...") | tap(x, y) -> screenshot again to verify. Use burst=true when meaningful=false but visual feedback looks transient. LIMITATIONS: iOS needs AXe (brew install cameroncooke/axe/axe) or IDB for accessibility/coordinate taps. Non-ASCII text skips fiber (Hermes); prefer testID. Pass `device` to target a specific simulator/emulator when multiple are available — call list_devices for the inventory. GOOD: tap({ testID: "login-btn" }); tap({ text: "Submit" }); tap({ x: 300, y: 600 }); tap({ x: 300, y: 600, native: true, device: "emulator-5554" }) LONG PRESS: tap({ testID: "row-3", duration: 800 }) holds the touch. BAD: tap({ text: "" }) or tap({ x: 0, y: 0 }) — missing a target. tap({ text: "Submit" }) without first screenshotting an ambiguous screen. SOURCE: need the file:line that renders an element? inspect_at_point(x, y).
| Name | Type | Req | Description |

| component | string | – | Component name match (case-insensitive substring, e.g. 'Button', 'MenuItem'). |
| device | string | – | Target device. Accepts (a) an iOS simulator UDID, (b) an Android adb serial like 'emulator-5554', (c) the iOS simulator or Android emulator/device name (substring match), or (d) a connected RN app's… |
| duration | number | – | Hold the touch for this many milliseconds instead of releasing it immediately — a long press. Use for context menus, drag starts, multi-select. React Native fires onLongPress at 500ms, so 800 is a sa… |
| index | number | – | Zero-based index when multiple elements match (default: 0). |
| maxTraversalDepth | number | – | Max parent levels to traverse when searching by component name (default: 15). Increase if your component is deeply wrapped (e.g. inside multiple HOCs/animation wrappers). |
| native | boolean | – | When true, tap coordinates directly via ADB/simctl without requiring a React Native connection. Useful for interacting with native UI, system dialogs, or non-RN apps. Requires x/y coordinates. |
| screenshot | boolean | – | Return post-tap image bytes in the response. Default true. Set to false to drop the PNG bytes — verification still runs (set verify=false to skip that too). Combine with verify=true to get the meanin… |
| strategy | string | – | "auto" (default) tries fiber -> accessibility -> OCR. Set explicitly to skip strategies you know will fail. |
| testID | string | – | Exact match on the element's testID prop. Also resolves Switch/checkbox elements (onValueChange), which have no onPress — the response then carries `switch.before/after/changed`, read back from the e… |
| text | string | – | Visible text to match (case-insensitive substring). ASCII only for fiber strategy; OCR handles non-ASCII. |
| verify | boolean | – | Run before/after screenshot diff to detect if the tap had a meaningful visual effect. Default: true for coordinate/accessibility/ocr strategies, false for fiber. Independent of `screenshot` — verify… |
| x | number | – | X coordinate in pixels (from screenshot). Must provide both x and y. |
| y | number | – | Y coordinate in pixels (from screenshot). Must provide both x and y. |

vault_capture ~295
Read a credential out of the running app straight into the vault. The value is never returned to you. PURPOSE: Cover credentials no captured request revealed — a cold session before the app has made an authenticated call, a token the app refreshed in the background, or one held somewhere no heuristic finds (keychain, expo-secure-store, an Apollo link). WHEN TO USE: http_request says no credential is known for an origin, or list_secrets shows the entry as EXPIRED after a re-login. WORKFLOW: vault_capture({ expression: "SecureStore.getItemAsync('access_token')", origin: "https://api.acme.io" }) -> http_request({ ..., auth: { secret: "api.acme.io" } }). GOOD: vault_capture({ expression: "store.getState().auth.token", origin: "https://api.acme.io" }) BAD: reading the same value with execute_in_app — that returns it into the transcript, permanently.
| Name | Type | Req | Description |
|---|---|---|---|
| device | string | – | Target device name (substring match). Omit for the default device. |
| expression | string | yes | JS evaluated in the app; its result goes to the vault, not to you. An async expression is awaited. |
| origin | string | yes | Absolute URL of the API this credential authenticates, e.g. https://api.acme.io. Binds the credential: it can only be sent back to this host. |
